Answer:
6 years.
Explanation:
We have been given that a house that costs $270,000 appreciates by 5% each year. We are asked to find the number of years it will take the house to be worth 350,000 by using equation
.
First of all let us divide both sides of our equation by 270.


Upon taking natural log of both sides of our equation we will get,

Using natural log property
we will get,



Since it will take more time than 5 years, so will round up our answer.

Therefore, in approximately 6 years the house will be worth $350,000.
